dc.description.abstract
Coherent electromagnetic control of quantum systems is usually done by electromagnetic radiation - which does not permit addressing single site-selected quantum systems, especially in the microwave range. In our proof of concept experiment we want to couple for the frst time the non-radiative electromagnetic near-feld of a spatially modulated electron beam to a quantum system in a coherent way as has been proposed lately. As the quantum system we use the unpaired electron spins of a free radical organic sample (Koelsch radical - α,γ-bisdiphenylene-β-phenylallyl) that is excited via the near-feld of the aloof electron beam. The readout of the spin excitation resembles a classic continuous wave electron spin resonance experiment and is done inductively via a microcoil (Fig 1.1) using a lock-in amplifer. The long term perspective of this experiment is the ability to coherently drive and investigate quantum systems in a spatial volume way below the difraction limit of traditional electromagnetic wave based excitation schemes. The spatially confned excitation using an electron beam could also be realized within an electron microscope. Within the last year we have been able to improve the setup, couple the electron beam to the microcoil and reduce noise sources as well as started preparations to cool down the microcoil setup to cryogenic temperatures for enhanced signal to noise ratio.
